    I'm going to go ahead and guess that you haven't searched the forums -- so we'll give you some time to go do that now.

    Won't fit... you're putting it in wrong, or it's not a SIM card. Take a picture of it.

    I got the SIM to go in. My other question was on how to restore my iPhone 3G without having to update it to 2.2.1

    You will have to find the 2.2 update on the internet and shift+click restore to get 2.2 on the phone.

    You don't need to unzip anything??
    After its downloaded save it to your desktop. Then in iTunes hold shift and click "restore" and select the firmware from your desktop.

    easy peasy lemon squeezy

    Okay, you're on a Mac, soooo....

    In Safari, go to "Safari" in the menu bar, select "Preferences", select the "General" tab, uncheck "Open safe files after downloading" then re-download the firmware you want. This will keep the firmware in once piece as a "*.ipsw.zip" file. Go to your downloads folder (or wherever you saved the file) and rename the extension to remove the ".zip" portion to be left with "(firmwarename).ipsw" . This should change the icon to a blue and white cube.

    Now, in iTunes, plug your iPhone in and hold "Option (alt)" key while clicking on "Restore" in the iPhone pane of iTunes. This will bring up a Finder window. Find your newly renamed .ipsw file, and open it.

    This will restore the iPhone with the selected firmware (I assume 2.2). After this is done, re-apply the jailbreak and unlock. Simple as that.
